Dominance of strong repulsive force among the molecules of the gas (Z = compressibility factor)

A.Depends on Z and Indicate by Z = 1

B.Depends on Z and indicated by Z > 1✓ Correct

C.Depends on Z and indicated by Z < 1

D.is independent of Z

Explanation

At high pressure all the gases have Z > 1. These are most difficult to compress. i.e., Dominance of strong repulsive forces among the molecules of the gas.
